Amazon Web Services (AWS)—a global leader in cloud computing—provides a wide variety of IT services. As you're financially responsible for whichever AWS services you use, it's important to establish sound financial monitoring to ensure that you're alerted to any changes before those changes become a financial burden. This course provides system administrators with an intermediate-level look at monitoring and metrics for the AWS platform. IT architect Sharif Nijim begins with monitoring tools like CloudWatch and includes coverage of VPC flow logs. He concludes with an introduction to Lambda and coverage of combining CloudWatch and Lambda.

This course is also part of a series designed to help you prepare for the AWS Certified SysOps Administrator – Associate certification exam.
